Staying at a hotel near Charles de Gaulle airport in the summer of 2002, I was struck by the sound of the traffic on the A1 motorway; it was loud and persistant, and enhanced by the recent rain storm. About 4am I recorded a series of samples.
Charles at Night uses one of these samples, and is modified with some resonant filters whose frequency and bandwidth are controlled by the Henon equation.
The piece is somewhat loud and liable to give the listener a headache. It however what I wanted.
